USB port that provides storage for firmware updates, output of the
◆
supportsave command and storage for configuration uploads and
downloads.
A system motherboard that features a Freescale MPC8548 Reduced
◆
Instruction Set Computer (RISC) CPU running @ 1.3GHz with
integrated peripherals that provides high performance with low
power consumption.
Inter-Switch Link (ISL) Trunking (licensable) allows up to eight
◆
ports (at 1G, 2G, 4G, or 8G speeds) between a pair of switches
combined to form a single, logical ISL with a speed of up to 64
Gbps (128 Gbps full duplex) for optimal bandwidth utilization and
load balancing.
Dynamic Path Selection (DPS), which optimizes fabric-wide
◆
performance and load balancing by automatically routing data to
the most efficient available path in the fabric.
Rack mount designed using existing rail kits (fixed, sliding, and
◆
mid-mount/Telco rail kits) on a 19" EIA rack.
Industry-leading extended distance support, which enables native
◆
Fibre Channel extension greater than (590) km.
Brocade Small Form-Factor Pluggable (SFP) or SFP+ optical
◆
transceivers that support any combination of Short Wavelength
(SWL), Long Wavelength (LWL), or Extended Long Wavelength
(ELWL) optical media among the switch ports.
Unicast, multicast (255 groups), and broadcast data traffic type
◆
support.
The Fabric Operating System (FOS), which delivers distributed
◆
intelligence throughout the network and enables a wide range of
value-added applications including Advanced Web Tools and
Zoning. Optional Fabric Services include: Adaptive Networking
with QoS, Extended Fabrics, Enhanced Group Management, Fabric
Watch, ISL Trunking, Integrated Routing, and End-to-End
Performance Monitoring (APM).
Port-to-port latency minimized to 2100 nanoseconds through the
◆
use of cut-through frame routing at 8Gbps.
Extensive diagnostics and system-monitoring capabilities for
◆
enhanced high Reliability, Availability, and Serviceability (RAS)
The EZSwitchSetup wizard that makes SAN configuration a 3-step
◆
point-and-click task.
